This sounds like a very widely known and discussed firmware problem. It happens with Linux, Windows, and Mac OS X, as well as various NAS boxes. It is seagate's fault. Of course I had only seen it mentioned for the 500GB, 750GB, 1TB and 1.5TB drives. Somehow yours seems like it should be a different series, but then again why should a firmware bug not be duplicated on all their drives. One discussion is here: http://techreport.com/discussions.x/15863 Seriously annoying for raid users of course when a drive falls out of the raid for no good reason. I seem to recall some people had found that if you disabled some part of the drive caching the problem seemed to go away (as did a lot of the drive's performance of course). -- Len Sorensen -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
